COTTON-PLANTER.

SPECIFICATION' forming part of Letters Patent No, 367,766, dated August2, 1887.

Application filed February 28, 1887.

To all whom it may concern..-

Be it known that I, HIRAM RoBErNs, of Little Rock, iu the county ofPulaski and State of Arkansas, have invented a certain new and usefulImprovement in Cotton Planters, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming part of this speeiication, and in which- Figure I is a top Viewof a machine embodying my invention. Fig. II is a longitudinal sectionat II II, Fig. I. Fig. III isa detail side view, of the sprocket-wheel,showing a short piece of the cheek-row cord. Fig. IV is a detailsectional View on the line IV IV, Fig. I. Fig. V is a detail rear viewof the central part of the axle, part in section.

This is a cotton-planter in which the dropping mechanism is actuated bybuttons on a check-row wire, cord, or cable, which causes theseed-wheels to turn, owing to the forward movement of the machine.

The seed boxes and wheels are made transversely adjustable to enable themachine to be used in planting rows of different distances asunder.

The tongue l is jointed to a central longitudinal bar, 4, ofa main framecomposed ofsaid central longitudinal bar, 4, side longitudinal bars, 4,and front and rear cross-bars, 2 and 3. The cross-bar2 has two series ofvertical boltholes,5,extending from the central bar toward the ends ofthe cross-bar, for bolts 6, by which the seed-box frames are connectedto it. The secdbox frames have each a pair of longitudinal bars, 7, andfront and rear crossbars, 8 and 9. rlhe crossbar 9 has a number ofvertical holes7 10, through which passes a bolt, 11, which also vpassesthrough one of the longitudinal side bars, 4, of the main frame. It willbe seen that by passing the bolts 6 and'll through others of the holes 5and 10 the frames may be adjusted so as to bring the seed-boxes 12nearer together. f,

In the lower parts of the seedboxes are the feed-wheels 13. Thesefeed-wheels have seedcavities 14, one of which is shown open to thecavity of the feed-box and another open to the spout 15. The feed-wheelis upon a shaft composed of two solid parts, 1G, and a central sleeve,17, forming a tube in which the ends of Serial No. 229,216. (No model.)

.the shaft) will turn both wheels.

The actuating device consists of a wheel, 19, having forked arms 20,which embrace the check-row wire, cord, cable, or chain 21. This wire 21has buttons 22, which as the machine is drawn forward engage the arms 20and turn the wheel 19 and the feed-wheels 13 onefourtli around, and thuscarry another of the seedcavities on each feed-wheel to its lowerposition, so that the contents drop into the spout 15 and into thefurrow at the rear of the plow or furro5v-opener 23.

The axle is,like the shaft, composed of a central sleeve or tubularpart, 24and two solid parts or end portions, 25, and is fixed to theframe by means of its central tubular part, 24. The end portions, 25,are telescoped'nto the tubular part andare heldin position therein bysetscrews, 26, which pass through the brackets 27, by which the part 21is held, through the .part 24,and bear against the parts 25. Thebrackets 27 are secured to the longitudinal bars. The wheels 2S turnfreely on the parts 25.

It will be understood that the wheels follow directl y in the fui-rowsinto which the seed has been dropped, and their concave rims com- -pressthe earth upon the seeds.

29 is a handlever, fulcrumed to the central bar, 4, of the frame andconnected by a rod, 30, to a standardhflrmly fixed to the tongue nearthejoint 32,by which the tongue is jointcdto the longitudinal centralbar, f1.

It will be seen that whenl the free end of the lever is moved backwardthe front end of the main frame 2 3 et israiscd, and with ,the frame thefurrow-opener, so that it penetrates the earth to a less depth. Aforward movement of the lever has, of course, a contrary effect. Thelever is held in the proper position by a drop-catch, 33, which engagesin-one of the notches 34 of a bar, 35. The catch is lifted by the usualrod, 36, aud small lever 37 upon the main lever 29.

The cotton-seed is always covered with a quantity of short cotton lint,which adheres fast to the seed, and which renders it necessary that theseed af each dropping should be separated from the mass in the seed-boxby a positive operation, which will forcibly separate the seeds from themass at the proper time and carry thern to the discharge-spout. This isaccomplished by the check-row `Wire with the sprocket-Wheel, shaft, andfeed-Wheel in a Way which could not be done by any dropping deviceactuated by the ground-wheels, because the resistance of the cotton-seedto the feed-wheel would cause the Wheels to slip at times,and'thus thedropping would be irregular and the hills would be out of place.

I claim as my invention- 1. The combination of the central longitudinalbar, 4, the side longitudinal bars, 4, the central sleeve, 17, extendingacross the bars, the shafts 16, journaled in the central sleeve,provided with feed-Wheels 13, having seedcavities 14, and wheels1.9,having forked arms 20, the seed-boxes 12, having suitable frames,spouts 15, and openers 23, substantially as described.

2. The combination ofthe central longitudinal bar, 4, the sidelongitudinal bars, 4, the central sleeve, 17, extending across the bars,the adjustable shafts 1G, journaled in lthe eentral sleeve, providedwith feed-Wheels 13 and wheels 19, the crossbar 3, the cross-bar 2,having series of bolt-holes 5, and the seed-boxes and frames, each seed-boxframe havinglongitudinal bars 7, cross-bar 8, and cross-bar 9, having aseries of bolt-holes, 10, substantially as described.

3. The combination ofthe central longitudicentral sleeve, 17, extendingacross the bars, the shafts 16, journaled in the central sleeve,provided with feed-Wheels, seed-box having frames, front cross-bar, y2,rear cross-bar, tubular part 24, extending across the longitudinal bars,and the axles 25, journaled in the tubular part,having furrow-closingWheels 28, substantially as described.

4. The combination of the central longitudinal bar, 4, the sidelongitudinalY bars, 4, the front perforated crossbar, 2, the rearcross-bar, 3, the central sleeve, 17, extending across the longitudinalbars in vrear of the front cross-bar, the tubular part 24, extendingacross the longitudinal bars in rear of the rear cross-bar, the shafts16, having feed-Wheels, the seedboxes, the frames supporting theseedboxes having longitudinal bars 7, front cross-bar, S, and perforatedrear cross-bar, 9, the axles 25, the furrowclosing wheels 28,furrow-openers 23, and seed-spouts 15, substantially as described.

5. The combination of the main frame comprising the central longitudinalbar, 4, the side longitudinal bars, 4", the front cross-bar, 2, the rearcross-bar, 3, and the tongue 1, jointed to the central longitudinalbar,having standard 31, the bar 35, having notches, the handlever 29,carrying small lever 37 and rod 3G, and the rod 30, connecting the leverwith the standard, substantially as described.
